I'm not too fond of bright GIF banners on websites, though i'm sure I could figure out a way that would make a version that looks decent. There'll be a slideshow on the front page, so one of the slides can serve this purpose if enough people want it. I'm not saying no to banners- just would prefer not to. They'd look very appropriate in the ghost net and maybe in the introductory material, though.
